Food Plant: Alnus glutinosa (Alder)

Egg: Underside of leaf

Mine: July, September - October

Notes: A gallery with frass partly dispersed, but sometimes in a thin line (as S.alnetella). The moths must be bred through to distinguish between this and S.alnetella. This mine illustrated may be S.alnetella as it has rather a narrow frass line.
